He isn’t ________ to take care of ________. A．old enough; himself B．enough old; himself C．old enough; him D．enough old; him 【答案】A 【详解】句意：这个男孩只有7岁。他还不够大，不能照顾自己。 old是形容词，enough修饰形容词时需后置，即放在形容词之后；当动词短语的宾语与主语指代同一人时，需使用反身代词himself。 3．He spoke ________ fast for me ________ understand. A．too; to B．so; that C．such; that D．enough; to 【答案】A 【详解】句意：他说得太快，我听不懂。 too…to…太……而不能……，too后接形容词/副词，to后接动词原形；so…that…如此……以至于……，that后需要接从句；such…that…如此……以至于……，that后需要接从句；enough…to…足够……可以做……，enough修饰形容词/副词时要放在被修饰词之后。第一空后“fast”为副词，第二空后“understand”为动词，应用too…to…表示“说得太快而听不懂”。 4．—Do you want to keep goldfish? —No, it is ________difficult ________take care of them. A．so; that B．not; enough to C．too; to D．such; that 【答案】C 【详解】句意：——你想养金鱼吗？——不，养它们太难了。 so…that…意为“如此……以至于……”，so后接形容词或副词，that后接从句；not…enough to…意为“不足以……”，其中enough前常加形容词或副词，to后接动词原形；too…to…意为“太……而不能……”，其中too后接形容词或副词，to后接动词原形；such…that…意为“如此……以至于……”，such后接名词，that后接从句。根据“difficult”是形容词，“take care of them”是动词短语，可知此处应用“too…to…”结构，表示“养它们太难了”。 5．—Do you want to keep goldfish?   —No. It’s ________ difficult ________ take good care of them.

A．preparing; to talking B．preparing; talking C．to prepare; talking D．preparing; to talk 【答案】D 【详解】句意：她当时正忙于准备考试，太忙了，没时间和我说话。 考查形容词短语。preparing正在准备，现在分词；to talking动词不定式；talking现在分词；to prepare动词不定式。be busy doing sth.“忙于做某事”，因此第一空填动名词形式preparing；too...to...表示“太……而不能……”，因此第二空需用不定式形式to talk。故选D。 7．The baby tiger is ________ to catch any animals alone. She is just days old now. A．young enough B．old enough C．too old D．too young 【答案】D 【详解】句意：这只小老虎太小了，还不能独自捕猎。她现在才出生几天。 考查“too...to...”结构。young enough足够年轻；old enough足够老；too old太老；too young太年轻。根据后句“She is just days old now.”可知，小老虎年龄太小，无法独自捕猎，应使用“too...to...”结构表示“太……而不能……”。故选D。 8．He is ________ tired ________ walk any further. A．too; to B．so; that C．enough; to D．very; to 【答案】A 【详解】句意：他太累了，不能再走更远了。 考查固定句型。too…to…太……而不能……，to后接动词原形；so…that…如此……以至于……，that后接完整的句子；enough…to…足够……去……，to后接动词原形；very…to…不是固定搭配。根据“walk any further”，表示“不能再走更远”，符合“太累而不能走”的逻辑。故选A。 9．—Children’s lives were too ________ to find enough time for the hobbies. —It is quite different after the “double reduction”. A．much B．boring C．enough D．full 【答案】D 【详解】句意：——孩子们的生活太充实了，以至于没有足够的时间发展爱好。——“双减”之后情况大不相同了。 考查形容词辨析。much许多；boring无聊的；enough充足的；full满的。根据“find enough time for the hobbies”可知，此处是否定含义“没有时间”，结合语境可推测，此处指生活太“忙碌”，“full”在此处表示“（时间）排满的，忙碌的”，符合语义。故选D。 10．The gate of the factory should be wider. It is ________for two cars to go through. A．too wide B．wide enough C．not too wide D．not wide enough 【答案】D 【详解】句意：工厂的大门应该更宽些。它不够宽，两辆车不能并排通过。 考查形容词和副词用法。too wide太宽了；wide enough足够宽；not too wide不太宽；not wide enough不够宽。根据“The gate of the factory should be wider.”可知，此处应该表示门不够宽。故选D。 11．Jack is ________ funny ________ make us happy after class.

A．late enough B．early enough C．too late to D．too early to 【答案】C 【详解】句意：虽然时间明显变得紧迫了，但解决问题还不太晚。 late enough足够晚；early enough足够早；too late to太晚而不能去……；too early to太早而不能去……。根据句中连词although可知，前后分句之间存在转折关系，尽管时间紧迫，但解决问题仍然来得及。固定结构too... to...，其否定形式not too...to...意为“还来得及做某事”，结合语境，“not too late to fix the problem”符合逻辑。 13．The new rule about school manners is _________ understand.

The line at the bank is _________ _________ for the impatient customers _________ _________ in. 【答案】 too long to wait 【详解】句意：银行的队伍不够短，无法让不耐烦的顾客排队等候。分析句子可知，该句进行同义转换，需要把原句中“isn’t short enough…to wait”替换为is too long…to wait即可，其中too是副词，修饰形容词long，to是不定式符号，后跟动词原形wait作结果状语，too…to…“太……以至于不能……”，固定搭配。故填too；long；to；wait。 42．这个女孩足够勇敢去面对困难。 The girl is ________ ________ to face difficulties. 【答案】 brave enough 【详解】原句中“足够勇敢”是关键词，表示“足够……去做某事”的常用结构是“be+形容词+enough to do sth.”，其中“勇敢”对应的英文单词是“brave”。故填brave；enough。 43．这个房间足够大，可以容纳 20 个人。 This room is ________ ________ ________ hold 20 people. 【答案】 big enough to 【详解】原句中“足够大，可以……”是关键短语，表示“足够……去做某事”的固定搭配是“形容词+enough+to do sth.”。本句主语为This room，系动词为is，因此形容词big作表语；enough修饰形容词时需后置；to引出不定式作结果状语。故填big; enough; to。 44．She is too young to understand this. (改为 so…that 结构)   She is ________ young ________ she ________ understand this. 【答案】 so that can’t 【详解】句意：她太年轻了，理解不了这个。原句的too…to…结构含义是“太……而不能……”，本身带否定意义。转换成要求的so…that…（如此……以至于……）结构时，结构为so + 形容词/副词 + that + 结果状语从句，因为原句是否定含义，所以从句要用否定，本句是一般现在时，因此第三空用表示“不能”的can’t。 45．He didn’t come because he was ill. (用 so 改写)   He was ill, ________ he ________ come. 【答案】 so didn’t 【详解】句意：他没来，因为他生病了。原句用because表原因，改写时用so表结果，要将原因和结果的顺序调换。so意为“所以”，连接两个分句；时态和否定含义均不变，故didn’t无需修改。 46．He is very clever. He can solve the problem easily. (合并为 enough to 结构)   He is ________ ________ ________ solve the problem easily. 【答案】 clever enough to 【详解】句意：他非常聪明，能够轻松地解决这个问题。“enough”在英语中修饰形容词时，要放在形容词的后面，构成“形容词 + enough + to do sth.”的结构，该结构表示“足够……去做某事”。按照“形容词 + enough + to do sth.”的结构，“clever”是形容词，放在“enough”前面，“to”后面接动词原形“solve”，所以依次填入“clever”“enough”“to”。 47．盲童接受教育是很重要的。 It is important for blind children ________ ________ ________. 【答案】 to receive education 【详解】原句中“接受教育”为关键信息，对应固定搭配receive education，句子使用It is + 形容词 + for sb. to do sth. 句型。 48．你帮助残疾人真是太好了。 It’s ________ ________ you ________ help the disabled. 【答案】 kind of to 【详解】原句中“太好了”是关键词。根据中英文对照可知，此处考查It’s + 形容词 + of sb. to do sth.的用法，表示 “某人做某事真是……的”，用于评价人的品质。 “好的”，对应形容词kind，符合“帮助残疾人” 这一行为所体现的品质。故填kind；of；to。 49．在公共场合大声喧哗是不礼貌的。 It’s ________ ________ speak loudly in public. 【答案】 impolite to 【详解】原句中“不礼貌的”是关键词。impolite“不礼貌的”，形容词作表语。此处是It固定句型，It作形式主语，动词不定式作真正主语，所以第二空填to。 50．与别人握手时脱下手套是一种礼貌。 It’s ______________________. 【答案】polite to take off your gloves when you shake hands with others 【详解】根据中英文对照，空格处缺“与别人握手时脱下手套是一种礼貌”，句型是“It is adj to do sth”。“礼貌”polite，形容词作表语；“脱下”take off，“手套”gloves；“当……时”when，引导时间状语从句，“与某人握手”shake hands with sb，“别人”others。故填polite to take off your gloves when you shake hands with others。 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 $ 5月第三次月考复习之单元语法综合练 (Units 5-6) Unit 5 Good Manners 单元语法（too...to...和enough...to...的用法） Unit 6 Sunshine for all 单元语法（ It’s +adj+（of或for...）+to do的用法） 一、单项选择 1．In many countries, people are _________ follow others instead of pushing past them when walking on crowded streets.
